Ttc after nuva ring

I was on nuva ring for about 2 1/2 years and I took it out around the middle of April. I have been having regular 31 day cycles with 4-5 day periods and tracking my ovulation with OPK and have been ovulating. My question is how long after you got off nuva ring did you conceive? I know every one is different so I’m just trying to find an average.
